对 117 种节肢动物和 17 种脊椎动物的调查显示，雄性生殖器具有相对较低的静态异速生长值的强烈趋势。这种趋势与性选择下其他结构的异速生长形成鲜明对比，后者通常表现出陡峭的异速生长斜率。与节肢动物相比，哺乳动物的低异速生殖器值的趋势不太一致。数据与之前对生殖器低异速斜率的“一刀切”解释不符，该解释基于女性选择的性选择，表明了更普遍的版本，包括自然选择和性选择，并涉及机械配合和刺激。关于节肢动物雌性生殖器的不太完整的数据表明存在类似的低异速生长斜率的趋势，并且也可以通过机械配合和刺激性一刀切的论点来解释。
A survey of 117 species of arthropods and 17 species of vertebrates showed a strong trend for male genitalia to have relatively low static allometric values. This trend contrasts with the allometry of other structures under sexual selection, which usually show steep allometric slopes. The trend to low allometric genital values is less consistent in mammals than in arthropods. Data not in accord with the previous the "one-size-fits-all" explanation for low allometric slopes in genitalia, which was based on sexual selection by female choice, suggest a more general version that includes both natural selection and sexual selection, and involves both mechanical fit and stimulation. Less-complete data on the female genitalia of arthropods suggest a trend to similar low allometric slopes, and may also be explained by mechanical fit and stimulatory one-size-fits-all arguments.
